Pulled from the ProfiLux Mini manual, page 23.
Section 6.1.2 Display Indications
Display of the current sensor values (-): When the minus symbol is displayed, the control has activated the corresponding switching socket (if present) to reduce the pH value.
Display of the current sensor values(+): When the plus symbol is displayed, the corresponding switching socket (if present) has activated the control to increase the pH value.
